Hi All,

The latest mainline kernel branch fails to build mips jazz_defconfig with
the error:

drivers/video/fbdev/g364fb.c:115:9: error: 'FB_DEFAULT_IOMEM_HELPERS' undeclared here (not in a function); did you mean 'FB_DEFAULT_IOMEM_OPS'?
  115 |         FB_DEFAULT_IOMEM_HELPERS,
      |         ^~~~~~~~~~~~~~~~~~~~~~~~
      |         FB_DEFAULT_IOMEM_OPS


git bisect pointed to 501126083855 ("fbdev/g364fb: Use fbdev I/O helpers").

Reverting the commit has fixed the build failure.

I will be happy to test any patch or provide any extra log if needed.
